An alarming method of an automatic alarming device for an electric scooter comprises the following steps:

firstly, a user needs to screw and take down the fixing bolt 33, then the user can take down the plugging plate 4 and take in the fixing bolt 33 and the plugging plate 4 together, then the user needs to grip the rotating handle 6 and pull the U-shaped pull rod 75 to one side far away from the limiting frame body 72, so as to stretch the second spring 77 through the limiting ring 76, meanwhile, the L-shaped plate 78 synchronously moves along with the U-shaped pull rod 75, so as to drive the positioning ratchet 79 to move, further to separate the positioning ratchet 79 from the positioning ratchet 74, when the positioning ratchet 79 is completely separated from the positioning ratchet 74, the user can slowly release the rotating handle 6, at the moment, the first spring 51 stretches, so as to drive the automatic alarm device body 5 to move towards the outer side of the inner cavity of the installation box body 2, further to drive the transverse plate 21 to synchronously move, and simultaneously to pull the traction rope 22 to synchronously move when the transverse plate 21 moves, the rotating handle 6 and the positioning ratchet wheel 74 are driven to synchronously rotate by the winding roller 71, so that the traction rope 22 is unwound from the upper end of the winding roller 71, when the transverse plate 21 moves to the outermost side, the automatic alarm device body 5 just completely moves to the outer side of the installation box body 2, then a user can loosen the rotating handle 6 and the U-shaped pull rod 75 completely, the second spring 77 contracts at the moment, so that the positioning ratchet 79 is driven to reset by the U-shaped pull rod 75, and the positioning ratchet 79 is just meshed with the positioning ratchet wheel 74 again;

step two, if the user can open the electric scooter body 1 and stand on the electric scooter body in sunny weather, then the user can hold the rotating handle 6 and the fixed handle with both hands to drive the electric scooter body 1; if in rainy and snowy weather, a user needs to rotate the rotating wheel 83 firstly, so that the user drives the screw rod 82 to rotate, the shielding plate 3 is driven to move towards one side far away from the rotating wheel 83 until the shielding plate 3 is moved to the upper end of the automatic alarm device body 5, then the user can drive the electric scooter body 1 by repeating the steps, at the moment, the shielding plate 3 can effectively separate the rain and the snow from the automatic alarm device body 5, so that the normal use of the automatic alarm device body 5 is ensured, and during driving, the automatic alarm device body 5 can automatically sense the front obstacle and timely send an alarm to the user;

step three, when the electric scooter body 1 is used in sunny weather, a user can rotate the rotating handle 6 in a reverse direction, so that the rotating handle drives the winding roller 71 and the positioning ratchet wheel 74 to rotate synchronously, the traction rope 22 is wound from the upper end of the winding roller 71, the transverse plate 21 is driven to do reset motion while the traction rope 22 is wound, the automatic alarm device body 5 is driven to do reset motion and extrude the first spring 51, when the automatic alarm device body 5 moves to an initial position, the positioning ratchet 79 is just meshed with the positioning ratchet wheel 74 again, then the user can hold the blocking plate 4 by hand and clamp the fixing block 41 in the fixing groove 31 again, and then the user can rotate the fixing bolt 33 in a reverse direction, so that the blocking plate is inserted in the fixing through hole 42 and the fixing hole 32 again; after electric scooter body 1 used in sleet weather, the user still need the antiport runner 83 after accomplishing the installation of shutoff board 4 to make it drive shielding plate 3 and do the motion that resets, move it to initial position until.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
